Adventurers have stumbled across a cave so enormous that it has its own weather system, complete with wispy clouds and lingering fog inside vast caverns. A team of expert cavers and photographers have been exploring the vast cave system in the Chongqing Province of China and have the first-ever photographs of the natural wonder. They were amazed to discover the entrance to the hidden Er Wang Dong cave system and were stunned when they managed to climb inside to see a space so large that it can contain a cloud.
The cave is so huge that it has its own weather system: Explorers discover a lost world with thick cloud and fogs trapped inside.
One of the team members of the cavers and photographers, caver Robbie Shone, from Manchester, said a few of the caves had previously been used by nitrate miners but had not been properly explored. The labyrinth of network, which includes 'Cloud Ladder Hall' measuring around 51,000 meters squared, has water sources and vegetation of the floor.

An intrepid cave explorer ascends a rope hanging from the Niubizi Tian Keng. This photograph is one of the first-ever image taken of one of a cave so large it has its own weather system. Photographer and caver Robbie Shone, from Manchester, was part of a team of 1 explorers on a month-long expedition that discovered the hidden system.
American speleologist (one who studies and explore caves) Erin Lynch struggles to pull her way across a raging torrent of white water, which is the main river in Quankou Dong. One of the explorers said that they had to be aware of high water levels inside the caves; especially when it rained heavily on the surface.
"It is always very special, knowing that you are the first to step into a cave of somewhere where nobody had previously seen, not knowing what you might find and discover.
Where else on Earth can still hold secrets and mysteries of discoveries? That's what I love so much about exploring." Mr Shone was particularly excited about the cave network's interior weather system.

The underground camp in Sang Wang Dong is cosy and warm, according to the cavers. Hot food and drink recharge weary and tired explorers who sleep in either suspended hammocks or on roll mats on the floor, before venturing out into the vast surroundings.
" I had never seen anything quite like the inside cloud ladder before" She said.
" Thick cloud and fogs in the upper half of the cave, where it gets trapped and unable to escape through the small passages in the roof, 250m above the ground. "
"It reminded me of being in an abandoned state quarrying North Wales in bad weather."
The cave system discovered is not the only one with clouds inside, as humidity rises inside the caverns into colder air to form clouds inside the giant, enclosed spaces.

level of development in San Wang Dong create a spectacle
mid-way through a section of cave called Crusty Duvets.
"The drainage catchment to these caves is massive and soon the caves can be extremely dangerous and impassable when it rains heavily on the surface. We have to be on high alert and vigilant at the level of rising water always."
Duncan Collis and Erin Lynch walk through a section of cave in San Wang Dong called the Sea of tranquillity. Here remains of old nitrate mining cover the floor in forms of dug-pits and unwanted soil.

Crystal clear pools and slow moving streams make it easier to explore Quankou Dong's main river passage in the huge network of caves that have not welcomed visitors in years.
